Researchers have developed Knowledge-Geometry Decoupling (KGD), a novel approach for improving recommendation systems that continuously adapt to changing user behavior. KGD addresses two key challenges: what knowledge to extract from user sequences and how to transfer this knowledge effectively to a continuously refreshed model. By introducing Behavioral Multi-Token Prediction (BMTP), KGD learns cleaner behavioral knowledge, and its decoupled parameter sets allow for independent model refreshing without compromising downstream task performance. This method has been successfully deployed by Shopee, leading to significant increases in gross merchandise value and advertising revenue. AI
IMPACT Improves recommendation system adaptability and performance, with demonstrated commercial value in e-commerce.
